> a better way of doing something

Your argument fails right here because you're supposing something that isn't true. LLMs are better than search engines for some things, but you're speaking as if they're a replacement for what came before. They're absolutely not. Reading books — going to the original source rather than relying on a stochastic facsimile — is never going to go away, even if some of us are too lazy to ever do so. Their loss.

Put another way: leaving aside non-practical aspects of the experience, the car does a better job of getting you from A to B than a horse does. An LLM does not 'do a better job' than a book. Maybe in some cases it's more useful, but it's simply not a replacement. Perhaps a combination is best: use the LLM to interpolate and find your way around the literature, and then go and hunt down the real source material. The same cannot be said of the car/horse comparison.
